Abstract
The present invention is directed to the hair care treatment compositions, including pre- and post-treatment compositions, containing select aryl alkanone compounds as quenching and/or chelating agents.
Claims31
An improved hair care composition wherein the improvement comprises the presence of an effective amount of at least one aryl alkanone compound having the Formula I
- wherein R1, R2, R3, R4 and R5 which may be the same or different, are each independently H, OH, or a C1-C8 linear or branched alkyl or alkoxy group, and R6 is CH3 to prevent or reduce hair damage or hair color fading as compared to the use of the same composition without the aryl alkanone wherein the effective amount of the aryl alkanone compound is characterized as being present at a weight ratio of from 25:1 to 1:25 based on the amount of oxidizing agents in the case of hair care composition including an oxidizing agent or to be used concurrent with an oxidizing agent containing hair care composition;
- otherwise the effective amount is from about 0.1 to 15 percent by weight based on the total weight of the hair care composition.
A method of preventing or protecting hair from photo-, thermal- or oxidative damage comprising applying to the hair a composition comprising an effective amount of at least one aryl alkanone compound having the Formula I
- wherein R1, R2, R3, R4 and R5 which may be the same or different, are each independently H, OH, or a C1-C8 linear or branched alkyl or alkoxy group, and R6 is CH3 prior to exposing the hair to conditions which effect or promote photo-, thermal- or oxidative damage, whereby less hair damage is found as compared to the hair exposed to those conditions without the application of the composition wherein the effective amount of the aryl alkanone compound is characterized as being from about 0.1 to 15 percent by weight of the composition.
A method of reducing the damage caused by hair treatment compositions comprising either (i) incorporating into the hair treatment composition an effective amount of at least one aryl alkanone compound having the Formula I
- wherein R1, R2, R3, R4 and R5 which may be the same or different, are each independently H, OH, or a C1-C8 linear or branched alkyl or alkoxy group, and R6 is CH3 prior to or concurrent with its application to the hair or (ii) treating the hair with a composition comprising at least one of the aforementioned aryl alkanones in an effective amount prior to or following the application of the hair treatment composition to the hair, whereby less hair damage is found as compared to the treated hair which has not also been treated with the aryl alkanone wherein the effective amount of the aryl alkanone compound is characterized as being present at a weight ratio of from 25:1 to 1:25 based on the amount of oxidizing agents in the case of hair care composition including an oxidizing agent or to be used concurrent with an oxidizing agent containing hair care composition;
- otherwise, the effective amount is from about 0.1 to 15 percent by weight based on the total weight of the hair care composition.
